Development Session Summary - 2025-12-14

Completed Work ✅

1. Fixed Flaky Integration Test ✅

  • File: icn/crates/icn-core/tests/topology_integration.rs
  • Issue: test_scope_aware_peer_sampling failing intermittently when run with other tests
  • Fix: Increased retry attempts from 20 to 40 and delay from 200ms to 250ms
  • Result: Test now passes reliably when run concurrently with other tests

2. Enhanced TypeScript SDK ✅

Added three major feature sets to @icn/client:

A. Batch Operations

  • batchPay() - Execute multiple payments efficiently
  • batchAddMembers() - Add multiple cooperative members at once
  • batchUpdateMembers() - Update multiple member roles/settings
  • Returns summary with succeeded/failed counts and detailed results

B. Query Builder (Fluent API)

  • queryHistory() returns HistoryQueryBuilder for complex queries
  • Methods: fromDid(), toDid(), minAmount(), maxAmount(), startDate(), endDate(), lastDays(), offset(), limit()
  • Chainable API: client.queryHistory('coop').fromDid('alice').lastDays(30).execute()

C. Event Filtering Helpers

  • EventFilter class with built-in filters:
    • payments() - Payment events only
    • proposals() - Governance events
    • members() - Member management events
    • byDid(did) - Events involving specific DID
    • byType(type) - Specific event types
    • and(...filters) - Combine with AND logic
    • or(...filters) - Combine with OR logic

  8. Transaction appears in history, badge disappears
  9. If sync fails → Red toast with error message, transaction marked failed
